I believe I was horniest when I was 15. I had been jacking off for six years, was 5'6', weighed 140 pounds, and had a dick that was 6.5' hard. I valued its appearence at all times, especially just after a good come.
When I was 15, I was perpetually horny and my dick was always semi-hard if I wasn't in the process of milking my prostate when it was so hard it hurt. I was a narcissistic exhibitionist greatly appreciating the appearance of my body and having someone else to share these attitudes. So I eagerly accepted the offer of my friend Sam to meet at his house after school for a jack off session. We did this on average about three times a week when we would strip naked, lube up with baby oil and jack away. This went on from the time we were 13 until 17 when our interest in girls began to predominate. Except for the orgasms, the greatest enjoyment happened after a fierce come when I was relaxing looking at my swollen, red glistening dick oozing come and knowing that Sam could see all that I saw. The memory of this peculiarity provoked by reading the stories on this site urged me to share it.
